Line T2 underground, Valencia

Fighting against water in a historic surrounding

Development of the work

A work of great physical and technical complexity, located in the historical centre of the city of Valencia (Spain), with a National Historical and Artistic Monument such as the Church of the Santos Juanes (estimated to be of Christian origin around 1240) and a jewel of Valencian modernism, the Central Market of Valencia (inaugurated in 1928).

Given the lack of space in the area, in addition to the marked tourist and commercial character, a 5-level underground car park was designed, under which a new underground station will be located for the future T2 line.

It is known that Valencia has a high phreatic level, which in combine with the great depths required, required the injection of high pressure grouting for the implementation of record length screen walls in Spain at that time.

In order to stabilize the ground with grouting, it was necessary to monitor the topography of nearby buildings, both historical and residential.
